EMANUEL r. SHIPMAN, or PHILADELPHIA, PENNSYLVANIA SOLDER CATCH PAN Application filed lebruary 16, 1929, Serial No. 340,375.

My invention relates to solder catch pans, more particularly for use of linemen and others required to form soldered joints on suspended cables or attach brackets, con-' nectors or other devices to cables, especially in connection with suspendedconductors of electric railways and main suspended cables for electric lighting systems.

The object of my invention is to provide means to catch the falling hot solder during the time the lineman is applying the solder to the suspended cable or wire and eliminate any possibility of v the solder in falling to the ground causing injury to ground men and pedestrians who may be passing under the wires or nearby when a strong wind is blowing. s

More particularly, my improvement embodies a catch pan made of electric non-conducting material I and in its preferable form has sides of heavy canvas and an internal bot-.

tom of woven asbestos or other heat resisting material such as chrome leather.

The pan is further provided with means to hold it in an eirtended condition when suspair of bars.

The suspension devices preferred comprise manila or other suitable rope secured to points distant apart about the upper ends of the reinforced side portions of the'pan and terminate at their free ends in a hook adapted to hook upon the suspended wire upon which i the solder is to be applied, theconstruction being such that the pan may be suspended nearer or" farther from the wire to suit the convenience of the operator, andto prevent escape of dropping solder.

The collapsible feature ing the extending bars of two of the sides and provided byhavarranged at the top at the bottom of the the pans must be conveyed in wagons or trucks with other equipment, and by such capacity to be collapsed they occupy a minimum of space and jured by the piling ment uponthem, which would la if they were required extended or open condition.

improved solder catch pan when to be are less liable to be inof other heavy equiprgely occur to remain in their full Aside from the more important use of my the work is performed upon suspended cables or conductors, my improvement is futher suitable for use of cable splicers in underground man-hole work, wherein theimproved catch pan prevents the loss of solder falling upon the bottom of the man-hole, and furthermore,

avoids the use of metallic construe tions which might be liable to produce short circuits.

My improvements comprehend the above and other features fully referred to details described hereinafter and more particularly pointed out in the claims.

eferring to the drawingsz Fig. 1 is a perspective view of a catch pan,

embodying my improvements, in suspended condition for use; F 1g. 2 1s a transverse SBClJIOH'OIl line 2-2 of Fig. 3; F ig.3 is a transv erse section on line 3+8 of Fig. 2; Fig. 4 is aperspective view showlng a special use of the suspension means; Fig. 5 isa perspective view of a modification of my improved solder catch pan;

and Fig. 6 is a sectional view of a portion of the same taken on line The 6-6 of Fig. 5. bottom 2 of the catch pan is formed of a layer of heavy canvas material with the four sides'turned upward as at 3 and 3a, the

former beinghemmed at their upper portions to form hem spaces 4 which resp ectively receive the spreading bars 5 andthe latter provided at their bottom portions with longitudinal spaces 6 in which the spreadin respectively located, these angles to the bars The side portions?) g bars 7 are bars being at right 5 but at a lower plane. having the hems 4 at their upper portions for the spreading bars 5 are reinforced by canvas lin ingsor inner parts 13,

these the stitches 4a which also form t and said inner linings 13 extend being stitched to the side portions 3 by he hems 4; downward remaining two sides is advantageous in that being soldered is and somewhat inward upon the bottom portion 2.

In respect to forming the longitudinal spaces 6 on the sides 3a, said spaces are formed by the attachment of a lining 8 of canvas stitched at 9 to the upper edge of the side portions 30 and again to its lower portion at the points 10 and 11. It is also to be understood that the corners of the side portions 3 and 3a are stitched together to make a general box-like shape to the catch pan when suspended, and moreover, the ends of the hem portion 4 and the space 6 are preferably sealed after the insertion of the spreading bars.

12 represents the interior bottom of the pan and is formed of a heat resisting material which is also a non-conductor of electricity, and in the preferred form is made of woven asbestos. This asbestos bottom is secured in position by the line of stitching 11 which attaches two of its side edges in position and also forms part of the spaces 6 hereinbefore referred to, and has its other edges secured to the canvas bottom by further lines of stitching 14 which also pass through and attach the lining portions 13 to the side portions 3.

While I have found woven asbestos fabric most desirable for the interior bottom of the catch pan, I do not limit my improved construction to the use of asbestos as other materials may be used such, for example, as chrome leather which has great heat resisting qualities.

Referring to the suspension means for the pan, the construction preferred is formed as follows: Each of the side portions 3, 3, is provided at its upper part with gromets 15 widely spaced apart and preferably extending through both the side portions 3 and their lining 13. Through said gromets a manila rope portion 16 is passed so that the two ends thereof extend inwardly and are spliced together at 17. One of the rope ends is further passed through the eye of an S hook 18 and spliced at 19 so that the hook is securely attached to the rope.

In practice, the catch pan may be suspend ed from the wires as indicated in Fig. 1, and it will be understood that such suspension need not be to the particular wire being soldered, for in most instances as, for example, in electric supply wires or those of telegraph systems, would involve a plurality of such wires upon the poles and, therefore, available to the operator. If, for any reason, it is desirable that the pan should be held close to the wire, where the soldering is being done, the suspension ropes may be wrapped about the cable and kept in the shortened condition by the hook preventing the unwrapping of the rope. as will be understood by reference to Fig. 4. The raising of the pan so that it is closer to the part desirable where the wind is strong and the hot solder might be blown laterally over the sides of the pan.

Another special advantage in the construction of my improved pan lies in the fact that while the spreading bars 5 are arranged at the upper portions of two of the sides of the pan and to which the suspension means are secured, the upper edges of the two remaining sides 3a are devoid of stiff spreading bars and consequently permit the wrists of the operator to manipulate the tools over said sides, they bending or adapting themselves to the movements of the hands of the operator without interfering with his manipulations and without materially disturbing the position of the pan, as would likely occur if the operation on the wire to be soldered was required to be performed over a rigid upper bar or edge of the sides of the pan.

It will be further appreciated that in transporting the pan, the same may be readily collapsed by folding inward the side portions 3a and. thereafter folding down the side portions 3.

As a modification of my improved insulating solder catch pan/I refer to Figs. 5 and 6. The modified construction therein shown comprises two end boards 3b flat at the top and curved on the underside and connected together by a curved bottom 2a having an inner lining 12a of asbestos or chrome leather which may be stitched to the canvas bottom 2a along the upper edges thereof. as at 20, and may be secured with the canvas along the curved under portions of the board ends 36 by staples or wood pins 21. (see Fig. 6). so that there is no metal work whatever in the make-up of the pan. The suspension means 17 in this modification is exactly the same as in the first described construction. but gromets will not be necessary. as the rone suspending devices may extend throu h holes 15a formed in the wooden ends themselves.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable. and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results. it is to be understood that I do not restrict myself to the details as the same are susceptible of modification in various particulars. without departing from the spirit or scope of the invention.

Having now described my invention. what I claim and desire to secure by Letters Patent is:

1. A solder catch pan comprising a shallow textile box-shaped body having the upper parts of two only of its opposite side portions provided with separate spreading means and also having separate spreading means at right angles to said sides but independently located at the two opposite sides of the bottom portion of the body,

tom portion of the body composed of a heat resisting and non-electrical conducting mawherein further,

terial, and suspension means connected with the side portions having the spreading means so constructed that the pan may be suspended with its bottom in a horizontal plane.
